Pressure Compensation:
Pcomp = a0 + ( b1 + c12 ? Tadc ) ? Padc + b ( c )
Using the evaluation sequence shown in Section 3.3:
c12x2
= c12 * Tadc
= 0.000790 * 507
= 0.40053
a1
= b1 + c12x2 = -2.37585 + 0.40053
= -1.97532
a1x1
y1
a2x2
= a1 * Padc
= a0 + a1x1
= b2 * Tadc
= -1.97532 * 410
= 2009.75 + (-809.8812)
= -0.92047 * 507
= -809.8812
= 1199.8688
= -466.67829
PComp = y1 + a2x2
= 1199.8688 + (-466.67829)
= 733.19051

Solder Recommendations
Use SAC solder alloy (i.e., Sn-Ag-Cu) with a melting point of about 217°C. It is recommended to use SAC305
(i.e., Sn-3.0 wt.% Ag-0.5 wt.% Cu).
Reflow
?
?
?
?
?
?
Ramp up rate: 2 to 3°C/s.
Preheat flat (soak): 110 to 130s.
Reflow peak temperature: 250 ° C to 260°C (depends on exact SAC alloy composition).
Time above 217°C: 40 to 90s (depends on board type, thermal mass of the board/quantities in the reflow).
Ramp down: 5 to 6°C/s.
Using an inert reflow environment (with O 2 level about 5 to 15 ppm).
